Abstract

A user terminal reads out encrypted contents to be authenticated from an encrypted content storage medium for storing the encrypted contents in association with management information and assigns data for forming the read out encrypted contents to the same hash function as that of the management device to calculate a first hash value. The management device acquires the calculated first hash value and management information from the user terminal, reads out, from a management information storage section for assigning the data for forming the encrypted contents which retain the authenticity to the hash function to store a second hash value which is a previously calculated hash value in association with the management information, the corresponding second hash value by using the acquired management information as a search key, authenticates whether the acquired first hash value and second hash value are matched, and permits a decoding processing if the result of the authentication shows that the first and second hash values are matched.
